NS103 Berry Gumbolt is a fully opaque saturated dark blue. It is well suited for stringer application and blown work. It is not susceptible to reduction and is not flame sensitive. For best results keep it in a neutral flame. It is a great backing for such colors as NS014 Irrid and NS015 Turquesa, and goes well with NS063 Canary.

An under-appreciated gem!

This is an awesome background/base for any frit that's super-saturated with metals, because it's "reactive" -- Berry Gumbolt itself doesn't change colors, but it somehow grabs the fume from other colors, making a hazy halo around each speck of, say, Aurora or Amazon Bronze. For even more awesomeness, after you've melted your frit in (and played with spot-oxidizing or reducing), encase with a light transparent like Ice Blue, Sublime, or GA Cobalt Lite.

Great saturation


Great saturated blue. I use it for seahawk fans



Absolutely bulletproof. Have used this color as a base/backing for 6 years love it. Great for beginners.

Love it


Another great backer that plays off of other colors. Very workable and forgiving.
